Abstract

Digital Dividend is the spectrum available from the release of very precious spectrum when full migration of analog terrestrial television transmission towards digital terrestrial television transmission has been fully undertaken. What makes Digital Dividend is extremely important is that the fact the spectrum located in lower UHF band below 1 GHz. Therefore, it is optimum in terms of the need of coverage and bandwidth. The main potential services in Digital Dividend are mobile broadband and digital terrestrial broadcasting. The objective of this study is to find out the minimum guard band and minimum distance between mobile broadband and digital terrestrial broadcasting. The interference analysis has been undertaken using SEAMCAT (Spectrum Engineering Advanced Monte-Carlo Analysis Tool) software. Several scenarios between DVB-T and E-UTRA, such as co-channel and adjacent-channel interferences, variation of distance between DVB-T and E-UTRA devices, and different directions of link have been studied. The results obtained provide some figure regarding the minimum guard-band required and minimum distance between DVB-T and E-UTRA systems.

数字红利UHF频段保护带干扰分析及DVB-T和E-UTRA的地理分离

数字红利是在模拟地面电视传输完全向数字地面电视传输迁移后，释放非常宝贵的频谱所获得的频谱。“数字红利”之所以重要，是因为它的频谱位于1ghz以下的UHF频段。因此，从覆盖和带宽的需求来看，它是最优的。“数字红利”的主要潜在业务是移动宽带和数字地面广播。本研究的目的是找出移动宽频与数字地面广播之间的最小保护频带和最小距离。使用seamat (Spectrum Engineering Advanced Monte-Carlo analysis Tool)软件进行干扰分析。研究了DVB-T和E-UTRA之间的同信道和邻接信道干扰、DVB-T和E-UTRA设备之间距离的变化以及不同链路方向等场景。所得结果提供了DVB-T和E-UTRA系统之间所需的最小保护频带和最小距离的一些数据。
